In present study, biodiesel was produced from landfill waste-derived oil by chemical transesterification process, to evaluate its potential as a renewable energy source for the first time. The free fatty acid percentage (FFA) in landfill waste oil is considered to be high, which was reduced by treating it with two different acids as catalyst, muriatic acid and phosphoric acid, in order to build a comparison between fatty acid methyl ester (FAME) contents. Further, it was treated with a base catalyst potassium hydroxide (KOH) to produce the final product. The FAME value of landfill oil when treated with muriatic acid was found to be 92.59%. The quality of biodiesel produced was analyzed by gas chromatography (GC), which indicated above 25.7% of conversion of oil into biodiesel when muriatic acid was used as a catalyst. The properties of the produced biodiesel were found to be in good agreement with ASTM D 6751 and EN 14214 standards. Various test fuels were prepared for the engine test by blending 10%, 20%, and 100% of landfill waste biodiesel in diesel on volumetric basis and designated as B10, B20, and B100, respectively. The brake thermal efficiency (BTE) of the engine was more while the exhaust emission was less except NOx with biodiesel and its blend (B10 and B20). Thus, landfill waste is a potential source of biodiesel, and blends of landfill waste up to 20% can be used for realizing better performance from the engine.
在本研究中，通过化学酯交换法从垃圾衍生油中生产生物柴油，首次评估其作为可再生能源的潜力。垃圾衍生油中的游离脂肪酸（FFA）含量较高，通过用两种不同的酸（盐酸和磷酸）作为催化剂处理，将其降低，以比较脂肪酸甲酯（FAME）的含量。然后，用碱催化剂氢氧化钾（KOH）对其进行处理以生产最终产品。用盐酸处理垃圾衍生油时，FAME 值为 92.59%。通过气相色谱（GC）分析生物柴油的质量，结果表明当使用盐酸作为催化剂时，油转化为生物柴油的转化率超过 25.7%。所生产的生物柴油的性能与 ASTM D 6751 和 EN 14214 标准非常吻合。通过按体积混合 10%、20%和 100%的垃圾衍生生物柴油制备各种测试燃料，并分别指定为 B10、B20 和 B100，用于发动机测试。与柴油相比，生物柴油及其混合物（B10 和 B20）的发动机制动热效率（BTE）更高，而废气排放（除了 NOx）则更少。因此，垃圾是生物柴油的潜在来源，垃圾衍生油的混合物高达 20%可以用于实现发动机更好的性能。
